(1) A graft copolymer latex obtained by the copolymerization of a rubbery diene polymer latex with an aromatic vinyl monomer and an acrylic monomer is mixed with (2) a copolymer latex having a glass transition point of -40.degree. to 10.degree. C. and a volume-average particle size of at least 0.5.mu. obtained by the copolymerization of an olefin with a vinyl ester of a fatty acid while they are maintained in the form of latex to precipitate a solid resin, whereby a thermoplastic resin composition is obtained. The total solid resin contains at least 11 wt. % of the rubbery diene polymer and at least 1 wt. % of the copolymer of olefin/vinyl ester of fatty acid.
